Expert Analysis
🏗️ Design & Build
Designed to sit entirely under the kitchen sink, out of sight, connected to a small dedicated tap on the counter. A genuinely different installation footprint from every wall-mounted unit in our lineup, suited to modular kitchens where visible appliances are a design concern.
⚡ Performance
7-stage RO purification with copper enhancement and AO Smith's claimed 2x water savings versus standard RO systems — solid core performance, though the small review sample limits how confidently we can speak to long-term reliability.
🥘 Indian Kitchen Fit
Modular kitchens increasingly prioritise hidden appliances, and this is the only product in our lineup built for that specific use case. It requires more involved installation — likely professional coordination with your modular kitchen setup — than a simple wall-mount unit.
💰 Value for Money
At ₹20,999, this is priced at the premium end of our lineup for a feature (hidden installation) that most buyers don't specifically need. Only choose this over a wall-mounted alternative if under-counter installation genuinely matters to your kitchen's design — and go in aware that the review base here is thin.
What Buyers Say

Check the counter-top tap seal periodically for leaks given the hidden main unit is less visible for casual inspection

AO Smith
AO Smith Z9 Pro RO Water Purifier (Ambient & Instant Hot)
If you specifically want instant hot water for tea, coffee, or baby formula alongside RO purification, the AO Smith Z9 Pro is the only genuine option in our lineup — nothing else here dispenses hot water. If you just want the best RO purifier and can boil water separately, the Native M2 Pro or KENT Grand RO get you there for meaningfully less.
AO Smith
AO Smith Z5 Pro RO Alkaline Water Purifier (CFM+SCMT)
The AO Smith Z5 Pro offers copper-fortified alkaline water across all major Indian water sources, but with only 162 reviews and just 1 unit left in stock at last check, we'd point most buyers toward the better-proven Native M1 (7,161 reviews, similar price) or KENT Grand RO instead, unless you specifically want this exact AO Smith model.
Native (Urban Company)
Native M2 Pro Water Purifier by Urban Company (Touch Dispensing + Battery)
The Native M2 Pro is the most feature-complete purifier in our lineup: touch-dispense presets, battery backup through power cuts, and real-time filter tracking, backed by a genuinely strong 4.4★ rating across 2,182 reviews. At ₹17,999 it is a premium buy, but the "no scheduled service for 2 years" model is a real departure from the AMC-dependent ownership most RO brands still use.
